![]() In the case of a full screen application such as a game, the DGPU will write to the entire framebuffer of the IGP. When an application calls for DGPU rendering, the DGPU writes output to the portion of the screen that the application occupies. In this way, both cards can render output to the same screen, even simultaneously. This is accomplished by connecting the laptop's screen to the framebuffer of the IGP only, and allowing the DGPU to write pages of memory directly into that framebuffer. Your laptop uses a technology called Nvidia Optimus to render video output from two GPUs (the integrated Intel graphics processor,, and the more powerful Nvidia graphics card ). I authored a question on this subject a few years ago, so I might as well chime in with what I know. I forgot to mention I did run the game with "use integrated GPU" and the results were the same. ![]() I suspect my Geforce is "connected" to the motherboard with the Intel Chipset -in between- ? Is there any way to circumvent this if this is true? What is going on and how can I fix this? I really don't understand this. yet, on an older laptop the game runs like a charm. I really don't know what the problem is and I really hate it that I can't play an old game at more than 25 fps yet all the new games (2005+) on a more playable framerate. net frameworks, windows updates, dependencies and DirectX End User Runtime (DX9) are all up to date and installed. I tried disabling my Intel Integrated HD Graphics:īut when I tried to run the game it gave me an error the there is no Harware Acceleration support (for a game from 1999 hehe)Īnd what suprises me here is that there is absolutely no GPU/manufaturer name and the default windows drivers are used.Īll my drivers are up to date, all VC++ redistributables. ![]() ![]() I also made sure my "default GPU" is set to the NVidia GPU. I tried looking into the NVidia CPL but it doesn't have as much options. My laptop has an RMB option on applications which allows you to specify with which GPU to run an application with:īut after launchin DXdiag with this option, or the second, I always get this screen: (however I always limit it in-game to 60) I can play all the newest games without problems, but when running a game called "Dark Reign 2" it runs at 25 FPS / ~20 FPS max (no matter if settings are lowest 640x480 or highest 1366x768), while on my older laptop with an i3-370M and a AMD Radeon HD Mobility 5740 it runs at 120 fps. I have recently bought an Toshiba Satellite P855-32X laptop.įirs thing after I did launch this laptop is ofcourse update all drivers to the newest ones.Ĭonfigure everything I needed and it works like a charm. ![]()
